1. Mortality HRs for dialysis modality (PD versus HD) in 23,718 incident dialysis patients using a marginal structural model (MSM) taking into account changes in dialysis modality and transplant censorship in the first 2 years (Supplemental Table 3).
Mortality HRs for dialysis modality (PD versus HD) in 23,718 incident dialysis patients using a marginal structural model (MSM) taking into account changes in dialysis modality and transplant censorship in the first 2 years (Supplemental Table 3). Model 1, inverse probability weight (IPW): age, baseline modality, and time-dependent modality (TD; stabilized IPW mean=1.06); model 2, IPW: age, sex, race, DM, baseline modality, and TD (stabilized IPW mean=1.06); model 3, IPW: age, sex, race, DM, baseline modality (Alb and Hgb), and TD modality (Alb and Hgb; stabilized IPW mean=1.29); MSM adjustment 1, IPW-adjusted (IPWs were calculated using different sets of variables); MSM adjustment 2, IPW + adding the same variables used to calculate IPWs to control for residual confounding; MSM adjustment 3, same as MSM adjustment 2 + additional confounders: marital status, employment, baseline comorbidities (COPD, cancer, hypertension, ability to ambulate, heart failure, and atherosclerotic heart disease), and baseline serum levels of ferritin, calcium, phosphorus, and nPCR.
